How can I cast a char to an object

My problem is that I am creating an expression tree and the datat that the binary tree holds is generic hence the object.
So I when it comes time to take this char from a char arryay and put it in my tree it need to be an object.
ex.
Object op= expn[ptr];
newTree=new binaryTree(op); also if it gets this far op is ether going to be a -,+,*,/, when it comes time to evaluate how can I can that object into an operatot or will I have use if statments comparing the objects.
thanks in advance

As pgeuens wrote, convert from char to java.lang.Character and vice-versa:
char[] expn;
Character op = new Character(expn[ptr]);
newTree = new binaryTree(op);
char c = ((Character)op).charValue();
if (c == '+')

How can we Restict the Char single value Variables with , , =

Hi Experts,
How can we Restict the Char value Variables with <, >, <= (without selecting Inverval or only passing single value)
For Example
We have a standard Query 0FIAR_C03_Q1005, in this
New Selection
"1 - 15 Days, Posting Date<=Key Date, Clearing Date>Key Date"
This is restricted with the
Clearing(0CLEAR_DATE)
<Clearing key date(0P_KEYD3) It is a single value SAP Exit Varible
PostingDate(0PSTNG_DATE)
<= Posting keydate(0P_KEYD3) It is a single value SAP Exit Varible
When seeing these 0P_KEYD3, 0P_KEYD3 variables in the New selection screen they looks like >0P_KEYD3, <=0PSTNG_DATE
if you define any custom variables these are looks like =ZV_DATE.
to enable < , >, <= symbols for variables what we need to do.
In other way
Say we created one variable ZV_DATE single value, processing type as customer exit.
for this we populated current day,
Now Requirement is we need to display the all the records which are <= current date,
instead of passing low and high values, i want to restrict the calday <=ZV_DATE
New selection
0calday
<=ZV_DATE
How can we achive this, this is how the business content report having the restrictions
Please sugget me.
Thanks
Chandra

Ok,
In the InfoObject 0calday in the query designer under the filter area, under characteristic restrictions right-click over that InfoObject (0calday).
In the next window (select Values for [0CALDAY] Calendar Day in the dropdown box for "Show" choose Value Ranges. Under the word "Between" dropdown box select "Less than or equal to"
Below that word click on the button of the dropdown box Select from list.
In the new window select instead of History Variables and double-click on your variable ZV_DATE.
Click on the right blue arrow to move it to the right.
And there you go.
Tip: It exists a SAP standard variable named 0DAT which is exactly the current date (don't need to use ZV_DATE variable).

How can I cast in runtime

Hi,
I have read many pages of this forum, but I haven't found answer to my problem. It is very simple.
Object o = new JDialog();
Class cl = JDialog.class;
JDialog jd = (JDialog)o;
jd = cl.cast(o);The last row go to compile time error, why? How can I cast, if my class is only available by a variable?
Thanks

There is no point in casting to a class if you don't plan to call a specific method on that class' interface.
Why are you casting to a class and you don't even know what it is? I can see not knowing what you are casting from, but not knowing what you are casting too makes no sense.Yes, I want to call a method of a given class, but - in the particulat context - only what I have is an instance (object) of that class. I didn't want to write all of my use case rather the final question to have to solve. I thought the object.cast() is the solution, but it don't work. Why? That is the question I am waiting for.
It think there is an interesting situation: if object.cast() don't operate, what is it's task? My knowledge may be not too much.

How can I use a progress bar in objective c mac

How can I use a progress bar in objective c mac? I have a code that downloads a file and I want to be able to let the progress bar increase by 1. A bit further on the code (to download the file) it needs to increase again. And so on...
My code
-(IBAction) downloadButtonPressed:(id)sender;{
    //get the path to the image that we're going to download
    NSURL *url = [NSURL URLWithString:@"https://www.dropbox.com/s/l6o07m48npxknt4/Cluedo.zip?dl=1"];
    //get the path to documents folder where we're going to save our image
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *DocumentsDirectory = [paths objectAtIndex:0];
    NSString *filePath = [DocumentsDirectory stringByAppendingPathComponent:@"Cluedo.zip"];
    //Download the file to memory
    NSData *data = [NSData dataWithContentsOfURL:url];
    NSError *error = nil;
    //Save it on the Documents directory
    [data writeToFile:filePath options:NSDataWritingAtomic error:&error];
    NSFileManager* fm = [NSFileManager defaultManager];
    NSString* zipPath = filePath;
    NSString* targetFolder = @"/Applications"; //this it the parent folder
    //where your zip's content
    //goes to (must exist)
    //create a new empty folder (unzipping will fail if any
    //of the payload files already exist at the target location)
    [fm createDirectoryAtPath:targetFolder withIntermediateDirectories:NO
                   attributes:nil error:NULL];
    //now create a unzip-task
    NSArray *arguments = [NSArray arrayWithObject:zipPath];
    NSTask *unzipTask = [[NSTask alloc] init];
    [unzipTask setLaunchPath:@"/usr/bin/unzip"];
    [unzipTask setCurrentDirectoryPath:targetFolder];
    [unzipTask setArguments:arguments];
    [unzipTask launch];
    //[unzipTask waitUntilExit]; //remove this to start the task concurrently

Your code really isn't suitable for a progress bar, not a real one anyway. Your code will spend about 99.9% of its time in the method "dataWithContentsOfURL:url". That is not a method you want to use in the real world. It is only for demos or proof of concept exercises. All network operations should be asynchronous. That gives you the ability to gracefully recover when there is a failure and also to do fancy things like display a progress bar and tell the user when the download is complete.
Once you get the asynchronous download logic working, then you can worry about the progress bar. The first thing you will need is the size of the file. Without that, all you can ever do is an indeterminate progress bar or spinner. If you have the size of the file, then you can keep track of how much of the file you have downloaded and update your progress bar with the percentage complete. Make sure to throttle it to no more than incrementing by 1% at a time. Otherwise, a large file or a file transferred in many small chunks, would waste too much time updating the progress bar for no change.

How can I cast a String to a char array?

My code is:
char []sender = new char[48];
String senderStr = "event_router_send";
sender=senderStr.toCharArray();The sender array's size will be changed to the String senderStr's length. Is there a better way to fill a array from a String object and keep the array's size.

sender[index++] = c;
}But why do you want to keep the array size in tact? What if the String has more characters in it than the array's size?

How can i cast array of string to int ?

How can i restrict user to access database object (procedure) or JSP

Hi
I have 9ias infrastructure 902, on win2k box with 9i DB.
and I have one PL/SQL web application and another J2EE application both are hosted by 9ias 902.
Now we are looking forward to couple both with SSO.
I have deloyed samples of both and works fine.
Each application have different set of users, i mean there is no common user.
How can i restrict user not to view the web page which is not authorised to them.
as far as i understand from the Grocery demo is pick the role (which is a string only) from OID and programaticall apply security via if else endif construct.
can any one through light upto my concern.
regards
[email protected]

Hey Mary
No i haven't try to do that via pl/sql....
as the our application is j2ee app... deployed in oc4j.. with sso and ldap....
still finding to do so....
what i have realized that LDAP is just to store user information in inverted tree... and one have to build separated access security mechnisum that will be applicable to j2ee system....
thanx...

How can i compare the values of the objects in a class?

hi ,
i am testing how to test the values of the two objects
this is the code i have return below.....
class Sample{
          String name;
          int age;
          Sample(String name,int age){
               this.name=name;
               this.age=age;
public class sample2{
          public static void main (String []arg){
               Sample one = new Sample("cat",20);
               Sample two = new Sample("cat",20);
how can i test that object one and two are equal.
can anyone clarify me about this?

Um, this part doesn't work, it will never return true.

It will :) try for example objectOne.equals(objectOne); and add a System.out.println() at that part. It will return there.
>
but this part, woah dude, that's some pretty slick code you got here:
I couldn't figure out how to do the compare inside the class, but I think I see how this works.
Not sure how I would do it for an object with more than one value to check though.
    if (obj instanceof EqualsExample) {               //Not the best implementation considering possible subclasses but the easiest.
EqualsExample temp = (EqualsExample) obj;
return (this.name.equals(temp.name)); //Always use the equals function when comparing strings!
} else {
return false;
You could add them in one massive return (this.something == temp.something && etc). Or you could split it in a series of if statements. It's really dependant on what kind of variables there are in your class.
Maybe you have an ArrayList you need to compare but also an id. then it would make more sense to check the id first and then possibly loop through the arraylist.
Hope it's a bit more clear :)

How can I have one row for each object?

Post Author: farnaz
CA Forum: WebIntelligence Reporting
I have 3 objcts that one of them is ID and second one is internal code and the third one is quantity.There is more than one value for each ID (becouse of internal code).I want to create a report based on ID and quantity (not based on internal code).I make a break on ID but the result shows me more than one row for each ID.so how can i have just one row for each ID?
another question:
how can I post screen shot of the results to my messag in forum?

Post Author: jsanzone
CA Forum: WebIntelligence Reporting
farnaz:
Have you tried to omit "internal code" from your grid? In normal circumstances, if you have "ID" and "Quantity" on the grid, then WebI will on its own summarize Quantity based on ID, however, this is provided that Quantity has been set up as a measure (or metric). The quickest way to tell if Quantity is a metric or not is to observe the color of its icon when you look at it in the data panel. If it is a purple (or sometimes appears as pink or fuscia) dot, then it's a measure, but if it is a blue box then it is a dimension. If you need Quantity as a measure then this will have to be modified at the universe (make it look like "sum(Quantity)" in the select phase of the object, and insure the object is defined as a number....

How can I get rfc822 format using Groupwise Object API(C++)?

I am newbie to Groupwise Object API, I want to get email in it's rfc822 form. How can I achieve this?

You need to have GW 8.0.0 DLL's.
The gwoapi10.h is an older header file.
You will need to use at least gwoapi_800.h.
gwoapi12.h is the header file for 7.0.3.
You can download newer header files at:

How can I convert a char to element? urgent !!!

I have a String put into an charArray. now I want to convert this char to an Element-Type. Whats the right way ???
thanks a lot for help

private String htmlTagFilter(String htf)There is absolutely no way to get 'attributes' starting with the above method declaration. String doesn't have that information and nothing you do to it will get it.
Now maybe the value of the string has text which describes an attribute. But if that is the case then you are going to have to go looking for it. That means parsing the string to find pieces and then extract it.
getAttributes()-Method from class javax.swing.text. There is no such class. I would guess you are referring to javax.swing.text.Element and its method getAttributes().
However that method returns an AttributeSet which is an interface. So to create your own AttributeSet you are going to have to know in great detail what exactly goes into that before you can parse a string and create it.
I will go out on a limb here and suggest that you don't really want to parse that String. You are trying to achieve an objective and got off on this tangent. And if you explain how you got the string and what you want to do with it, maybe some one could explain how to do what you want.

How can I casting from parent class to children class

Dear,
Could someone help me to casting from parent class to children class.
I have class like this
class parent{
String name;
String id;
public String getId() {
return id;
public void setId(String id) {
this.id = id;
public String getName() {
return name;
public void setName(String name) {
this.name = name;
class children extends parent{
String address;
public String getAddress() {
return address;
public void setAddress(String address) {
this.address = address;
public children() {
public children(parent p) {
//Do init super class here
In the constructor
public children(parent p) {
//Do init super class here
I like to init super class by object p (this is instance of parent class). The way to do is using:
public children(parent p) {
super.setId(p.getId());
super.setName(p.getName());
But I don't like this, because, for example I have parent class with over 30 proberties, it take time to do like that.
There are any way to use super operation to init parent class, for example super = p;
Could you show me the way.
Thanks alot

If I understand your question correctly, you are in need of a copy constructor for you class Parent. A copy constructor behaves like this:
   Parent one = new Parent();
   one.setName("...");
   //... and all other properties of interest
   Parent two = new Parent(one);
   //Now two != one, but one.getName().equals(two.getName) for property name and all othersThe copy constructor is programmed in the Parent class, more later. Then for your child class you can use it as follows
   public class Children extends Parent {
       public Children(Parent p) {
          super(p);
   }There are at least 3 ways of programming a copy constructor:
1. Just bite the bullet: type the assignment for each field this.name = p.getName()
2. Use reflection to find all common setters/getters dynamically and assign using them
3. Use a code generator that uses 2 to give you the code for solution 1 for you to paste in.
If you find doing this a lot, there are frameworks that can do these mappings, like Dozer
(PS be carefull with Date fields, don't copy the reference but create a new and equals instance, the dirty way would be this.birthdate = new Date(p.getBirthdate.getTime()); )

How can I Retrieve special chars from a HTTP Request??

Hi,
I want to retrieve special chars from a request
Chars like accents used in spanish languages or symbols?
Is there any way to do it
Thanks in advance
Alejandro Arredondo

This is my problem
For example:
This is my form:
<form>
<input type="text" name="test">
</form>
I do write a char on the text area. Something like "?" or "?"
or some words with accents
When I retrieve the value with
String value = request.getParameter("test");
and print it
out.println("TEST= " + test);
It prints another symbol that isn't the one I sent in my form.
why?
Thanks
